Title: Lead material for semiconductor device
Inventor: AKASAKA KIICHI
IPC: C22C9/00
Filed: 1980-10-15
Abstract: PURPOSE:To inexpensively produce a lead having excellent characteristics such as heat resistance, tensile strength, conductivity, etc. by employing as blank for lead frame an alloy of with predetermined ranges of Zn, Sn and Fe. CONSTITUTION:Elements of Zn, Sn, and Fe are contained 0.5-3.0wt% in the blank of a lead frame forming an IC or the like, with residue of Cu as a Cu alloy. The additions of Sn and Fe improve the strength and heat resistance, Zn improves the strength and the quality in the ingot. When the elements are contained less than 0.5wt%, sufficient strength and heat resistance cannot be obtained, while when the elements are contained more than 3.0wt%, the thermal and electrical conductivities and bending workability are lowered. For example, a plate of 0.3mm.thick can be formed by facing work of an ingot made of raw alloy, hot working it, then annealing and cold rolling it repeatedly. In this manner, the lead material of desired characteristics can be inexpensively produced.

Title: Elevating device of ceiling panel or suction grill
Inventor: FUJIWARA TATSUO
IPC: F24F13/20
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To improve an accommodating ability of a suction grill. SOLUTION: Wires suspending both ends of a suction grill are independently given a tension by means of tensioners. The tensioner 16 is provided with a movable roller 28 and a fixed roller 30. The movable roller 28 is biased by a spring 29 in a direction opposite to the fixed roller 30. The spring force of the spring 29 is set to a value greater than the component force of load of the suction grill applied to the spring 29 and smaller than the component force of a pulling force caused by a spring device and applied to the spring 29. Due to such a construction, when an imbalance takes place between windings of both wires by the spring devices so that the side of the suction grill adjacent to the wire 12 is not completely accommodated in a ceiling panel, the wire wound around the movable roller 28 and the fixed roller 30 is further pulled up by the extension of the spring 29.  Accordingly, the entire suction grill is completely accommodated in the ceiling panel.
